8T49N205A-009NLGI8

Overview

The 8T49N205A-009NLGI8 is a frequency synthesizer and clock generator from the FemtoClock family, manufactured by Renesas Electronics. It operates as a clock/timing component designed for precise frequency synthesis and jitter cleaning applications. The device is housed in a 40-VFQFN exposed pad package and supports frequencies up to 1.3 GHz. This specific part number is currently listed with a 'Last Time Buy' status, indicating it is no longer actively promoted for new designs.

Feature Summary

• Provides low-jitter clock generation and frequency synthesis capabilities
• Integrates phase-locked loop (PLL) technology for signal stability
• Designed for high-performance timing requirements in digital systems

Applications

• High-speed data communication interfaces
• Network synchronization equipment
• Test and measurement instrumentation

Procurement Notes

Verify current availability status carefully, as this component is designated as Last Time Buy. Confirm final order quantities with the manufacturer or authorized distributors before committing to purchase. Ensure that the 40-VFQFN package dimensions match your PCB layout requirements. Check for any pending production change notices that may affect long-term supply chain stability.

Selection Notes

Consider the 8T49N205A series characteristics when evaluating alternatives, focusing on the 1.3 GHz operational limit and VFQFN packaging. Since this specific suffix variant is in last-time-buy status, engineers should review the broader 8T49N205A family datasheet for pin-compatible or functionally similar replacements that are actively supported for future production runs.

Part Context

This component belongs to the Renesas FemtoClock series, which specializes in precision clock generation and jitter attenuation. The 8T49N205A model line is engineered for applications requiring strict timing accuracy and low phase noise. As a frequency translator IC, it serves as a critical timing reference source within complex electronic architectures.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation due to the Last Time Buy status. Engineers should consult the official Renesas cross-reference guide for the 8T49N205A family to identify active equivalents.
